Since this morning, have upped the CPU to 450MHz and tightened the timings back to how they were before. My memtest floppy has stopped working (or the floppy drive) so I can’t check the RAM again. But I’m still getting into windows and doing benchmarks no problem.

3577 3d marks (forgot to take a pic) and 7304 CPU marks. The 3d score is about 5% higher than 83 x 5.5

In dos, my results are a little worse than the benchmarks I made back in Jan this year

Current

Earlier this year

I seem to have lost some FSB somewhere. Not sure where it’s gone 😅 it sometimes shows a 99MHz FSB but I’ve not seen it over 100 since I’ve been playing with it again. Weird! But this will stop me hitting 600Mhz if I can’t find the cause

A small snag but something I was expecting - I have lost a lot of base mem by having the IDE card installed; 568k with cd and mouse driver. I was at around 600k before

I was expecting to lose some from the upper men, but It’s taken 11k from the total base memory and well, I now only have 629k instead of 640k. I searched on here and this is apparently something that I should have expected. The memory map on checkit says there is no data here. Confirmed with debug. What’s it doing??

The reserved area starts from 9d3f:0010. First hex value is set as 0B, then nothing. It doesn’t always start at the same place between boot-ups
